With a crossover story arc between Grey’s Anatomy and Private Practice planned for February, Grey’s Anatomy star Sandra Oh talked to People about what she calls the “Crossover crazy!” plans of executive producer Shonda Rhimes.

One thing we know for sure, and have long expected, is that Kate Walsh’s Dr. Addison Montgomery - who split from Seattle Grace to launch the spin-off and made a return trip to Grey's Anatomy last spring - will be back in her old OR.

Interestingly, Oh revealed that Patrick Dempsey’s Dr. Derek Shepherd will likely be making the journey to California's Oceanside Wellness Center, as well.

“It has to do with Addison,” she said. “I think the Chief is going to visit, too,” she added, referring to Dr. Richard Webber (James Pickens, Jr.).

Oh also has a suggestion for the writers in case they ever want to send her character to Oceanside to hook up with a handsome doctor.

“Paul Adelstein’s character,” she says. “Cristina Yang would have great scenes with Cooper. They’d just wrestle the whole time!”

But back at Seattle Grace, Cristina already has a budding relationship with ex-military doctor Owen Hunt, played by Kevin McKidd.

The pair shared a steamy kiss early on in the Season Five premiere, but Oh likes that the two of them have not rushed into becoming an instant McCouple: “It’s a nice, slow romance,” she says.
